RIVETING IRON Filed OCb. l0, 1929 Patented May 5, 1931` UNITED STATES nIvEfrING InoN Application filed october 1o, 1929. serial No. 398,716.

The present invention relates to riveting irons and the like and more particularly to riveting irons adapted for use in combination with an air-driven riveting hammer.

An object of this invention is to provide a riveting iron of this character which may be adapted for use in constructions where the use of a hot rivet is impossible and particularly where a metal frame or the like is to be riveted to a wooden or other combustible structure.

Another object of this invention is to provide a device of this character which is readily transported or moved from point to point, being of suflicient lightness in weight to make the device practical for use in structureswhere the present riveting iron is exceedingly cumbersome and diiiicult to use.

A further object of this invention is to provide a device of this character wherein means are provided in the base of theV device y for securely holding the same in adjusted position;

The above and various other objects and advantages of this invention will in part be understood from and inpart described in the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing wherein Fig. 1 is a sectional View ofa riveting iron constructed according to the present invention removably `mounted on a beam, also shown in cross section.

Fig. 2 is a plan view of the device.

Fig. 3 is a plan view of the cam. A

Fig. 4 is a sectional viewtaken on the line 4-4 of Fig. 3.

Fig. 5 is a fragmentary plan view of the forward end of the handle;

Referring to the drawing, the numeral 10 designates a section of framework or beam which is secured to a floor structure 11 or the like by the rivets 12 which have their heads 13 countersunk in the wood 11, and the lower end 14 of the rivet 12 is formed into the shape of a normal rivet head 14 which bears against an inwardly extending flange 15 which is secured to the frame 10 by rivets 16 or the like.

A base 17 for a riveting iron is provided with a plurality of slots 18V which preferably extend in horizontal relation to the base, and a sleeve 19 or the like is mounted in a substantially vertical position on the base. It will, of course, be understood that the base 17 and the sleeve 19 may be constructed of any suitable material but preferably of lmetal or thelike, and may be formed as a unit.

A shaft 2O is slidably'mounted in the sleeve 19 and is adapted at its lower end to protrude 60 from the lower end of the sleeve andextend upwardly from the upward end of the sleeve. The upperend of the shaft 20 is provided with a rivet setting `tool 2l'or the like which may be of any suitable configuration so as to produce the desired shape ofthe head 14 of the rivet. i

A cam 22 is pivotally mounted on the base 17 anda handle 23 is secured to said cam and extends outwardly of thebase so that the cam may be turned upon its pivot 24. The lower end of the shaft 20 is angularly inclined as at 25 so as to conform to the configuration of the cam and to bear against the inclined surface of the cam when'it is 75 moved on its pivot.,

In the operation of this device, the base 17 7 is preferably removably mounted in the frame 10 ina substantially vertical position so that theV rivet setting member 21 is in `so alignment with the rivet `14which itis desired to secure in position. The cam 22 is turned on its pivot 24 by means of the handle 23 so as to move the shaft 20 upwardly and engage the rivet 12. A11 air riveting ham- S5 mer or Vthe like is adapted to bear against the upper end of the rivet and by striking Vthe upper end of the rivet, the lower end thereof is turned over to conform to the configuration of the rivet setting tool and thereby firmly engages iange 15 against the" wooden structure 11. VAs the lower end of the rivet 12`is gradually turned over, the handle 23 is moved horizontally so as to A Y turnthecam on its pivot and force the shaft 9^- 2Ov upwardly toV constantly bear against the W lower end ofthe rivet. i l v The cam 22 may be provided with an opening 26, whichin the presentY preferred em-y bodiment is preferablysquare, and the for- 10ulparlarsi' OFFICE- in the details of construction and design of Y the above specifically described embodiment of the invention without ,departing from the spirit thereof, such changes and modifications being ,restricted ronly yby the scope of the following claims.

I claim l. A riveting iron comprising Aa base, said base having a plurality of grooves, a lsleeve upstanding from said base, `a shaft slidably mounted in said sleeve and in said base, a rivet head mounted on said shaft `on the upper end thereof, the lower end of 4said shaft being inclined with respect to the longitudinal axis thereof, a cam pivotally mounted on said base and engaging :said lower end of said shaft, and means for turning said cam whereby vto move the shaft up wardly.

2. A riveting iron comprising a base, said base having a plurality of horizontally arranged grooves, Aa ,shaft mounted on said base for vertical movement therein, said j shaft `being mounted on said base in offset relation to said grooves, rivet setting means on said shaft and adapted for movement therewith, and cam means pivotally mounted on said base and engaging the shaft.

4to; 3. A riveting iron comprising a base, said base having a plurality of grooves, a sleeve moiuited .on the base in odset relation to the grooved portion of the base and extending upwardly therefrom, a shaft slidably mountf 3ed in the sleeve, vrivet setting mea-ns mounted on the outer end of said shaft, cam means pivotally mounted on the base and adapted for horizontal rotation thereon, the lower end of said shaft being angular-,ly inclined `so as to bear against the inclined surface of said cam and means for turning the cam oIl its pivot whereby to move the shaft upwardly.

4. A riveting iron comprising a grooved hase, a shaft slidably mounted in said base and offset from said grooved portion of said base, rivet setting means kon the outer end of said shaft and operating means Yengaging the lower end of said shaft.

2 5. A riveting iron comprising `a base, said base having a plurality of grooves therein, a sleeve opstanding from said base and positioned in offset relation Ato the grooved portion, a shaft slidably mounted in said sleeve,

rivet setting means mounted on the outer Lacasse signature.
